Those who currently use vs05 or vs08, all of them facing a problem to integrate with new components, just think about asp.net mvc this important feature of asp.net is not included in vs2008 nor its sp1. So we have to implement it later by installing, and like asp.net mvc we all have to install separately silver light sdk 3.0 and silver light toolkit. And most important problem solved which is SQLSERVER problem. Now we can use directly sql2008 no etc installation needed.
but visual sudio 2010 is most useful for them who have interest to enter new world of programming like F#. yes, F# is with visual studio 2010, and u can easily learn f# because of visual studio help which is based on a strong library.
If u r a silver light developer , i think visual studio 2010 is not for u. It can’t give u anything new . MICROSOFT EXPRESSION BLEND STUDIO is best and better than visual studio 2010.
in VS2010 we can use .net framework 4.0, can use a strong library of c#, visual basic. many new components, Actually it presents a new dimension of developing .
So Now goodbye vs2008 or 05. Now is time for vs10.
